Background/Objectives: Recent lifestyle and dietary changes, driven by health awareness and ecological concerns, have led to the rise in numerous type of diets, which can promote well-being but may also contribute to Orthorexia Nervosa (ON), which have been suggested to be linked to autism spectrum disorder. This study aimed to explore the relationship between autistic traits, social camouflaging, and orthorexic tendencies in female university students, focusing on how these factors intersect with specific dietary habits. Methods: 554 female students were recruited via an online survey and assessed with the Adult Autism Subthreshold (AdAS) Spectrum, the Camouflaging Autistic Traits Questionnaire (CAT-Q), and the ORTO-R. Participants were categorized into four groups based on AdAS Spectrum and CAT-Q quartiles. Results: Vegans and vegetarians exhibited higher orthorexic tendencies and specific autistic traits. High scorers on the AdAS Spectrum and CAT-Q also showed higher ORTO-R scores, with both AdAS Spectrum and CAT-Q total scores, as well as certain domains, serving as significant positive predictors of higher ORTO-R scores. Notably, the AdAS Spectrum total score had a significant direct and indirect effect (through the CAT-Q) on the ORTO-R total score. Conclusions: The study found significant associations between autistic traits, social camouflaging behaviors, and orthorexic tendencies in female university students. These findings suggest that the strict dietary behaviors and rigid thinking characteristic of orthorexia may be influenced by underlying autistic features, highlighting the need for further research into the intersection of autism and eating disorders.
